4 Claims.

My invention relates to machines for applying jackets to ice cream cones and it particularly has reference to the complete machine which constitutes the subject matter of my original application Serial No. 483,075, filed April 14, 1943, and of which application the present one is a division.

The present invention deals with that part of the complete machine which takes the wrappers or jackets in an inverted position from a jacket supplying magazine, conveys the jackets from the magazine and deposits the jackets, right end up, in a receiver ready to receive the cones to be jacketed.

In general the invention has for its object to provide a mechanism for the purpose stated of a simple, effective and eflicient design that is pecul arly adapted for use in the machine of my original application although capable of other uses if desired.

Other objects will in part be obvious and in part be pointed out hereinafter.

To the attainment of the aforesaid objects and ends the invention further resides in those novel details of construction, combination and arrangement of parts all of which will be first fully described hereinafter and then be specifically pointed out in the appendedclaims, reference being had to the accompanying drawings, in which:

Fig. 1 is a part side elevation and part. vertical section of so much of the cone jacket applying machine of my original application as is necessary to illustrate the present invention, the jacket transfer frame being in one extreme position, i. e. that in which it receives a jacket.

Fig. 2 is a detail view similar to .Fig. 1 with .the transfer frame in its other extreme position in full lines and in an intermediate position in dotted lines.

Fig. 3 is an enlarged detail sectional view hereinafter specifically referred to.

In the drawings, in which like numerals and letters of reference "indicate like parts in all the figures, the same reference numbers and letters of reference have been used as for corresponding parts in my original application.

In the drawings I6 designates the main cam shaft of the machine on which is the cam 11 that operates the transfer mechanism in harmony with the other parts of the complete machine. A part of the main frame of the machine is shown at 33 and the sub-frame on which the cone dispensing mechanism, etc., is mounted is shown at 34 and 35, while 40, 4i) indicate the upright bars on which the plates 4| that carry the dispensing devices shafts 42, 43, 41, 52 are mounted. The cones are indicated by the letter The jacket magazine lill is mounted on a bracket I06. The jacket removing plugs I29 are carried on plug carriers I30 and are rec procated into and out of the magazine by a suitable cam .(not shown) operating the connecting rod I84, the jackets 20 being caused to adhere to the plugs I29 while being removed from the stack and placed on the fingers 12'! of the transfer mechanism as will later more fully appear. 94 is the receiver or mold into which the jackets w are deposited by the mechanism which constitutes the subject matter. of this application.

The swinging frame of the jacket transfer mechanism carries a finger carrying shaft II3 .on which a set of rigid fingers i2? is secured by set screws I'II, there being one finger for each jacket tube I01. A bridge member composed of two or more arms I I6 connected by a cross bar .I I1, is freely pivoted on the shaft H3. The bar It! carries a set of spring fingers IE8, one for each finger I21, and these fingers H8 are continuously pressed toward their associated fingers I21 by a leaf spring I28 that is fastened to one of the fingers I21 (Fig. 3).

An arm H4 is secured to the shaft H3 and carries a roller H5 to cooperate with cam track II2, while .a rigid arm .IZS, on the bar Ill, cooperates with a stop arm .I25 secured to one of the frame bars.

One .or both (one only being shown) of the frame bars I20 may be extended and provided with a notch I 2! to serve as a stop or guide in adjusting the maximum elevation of the plug carrier I30.

An arm I44 is secured to the shaft M3 by a set screw I22 and carries a stop lug I46 that may be engaged with the adjacent bar I20 when in the position of Fig. 2 and when the shaft H3 is turned counter clockwise in Fig. 2 and after the roller 'II5 leaves the end of the cam track IIZ, under the influence of the spring I45. The spring is anchored to frame I26 and to the arm I44 as shown.

The track H2 is carried by a bracket II! secured to a block III). The plugs I29 have suction passages which communicate with the chambered carrier I30 and are connected with a suitable source of suction (see original application) at proper times. The frame I20 of the transfer mechanism is pivoted at H9 and is moved to the position shown in Fig. 1 by a spring I23. An arm I24 on the shaft is connected to a connecting rod 20 that has a roller 23 to engage the cam II, by which the frame I20 is swun at the proper time from the position of Fig. 1 to the position of Fig. 2.

Operation Assume the parts to be positioned as in Fig. 1. The plug I29 will have just received a jacket w (see also dotted lines Fig. 3). turning clockwise in Fig. 1, pulls down on rod 20 the frame I20 is swung from right to left.

As the frame I 2|] moves from the position of Fig. 1, the arm I26 will have left the stop I25 and spring I28 will have brought finger H8 into pressure contact with the jacket on finger I21 to hold the jacket on the finger. By the time the parts reach the position of Fig. 2 the plug carrier will have reached its lowermost position and be starting up again; frame I20 and its carried parts will have reached the vertical position where the roller H5 is about to leave the track H2; the mold will be closing and will be fully closed before roller I I5 leaves track H2. On leaving the dotted position of Fig. 2, the roller H5 leaves the track H2 whereupon the spring I45 turns the shaft H3 counter clockwise to revert the jacket; as soon as the arm I26 strikes the stop I03 the finger H8 will be released from the jacket and the jacket will be thrown into the mold small end down (see full lines in Fig. 2).

At the proper time the frame I20 swings back to the position of Fig. 1 so that the fingers may receive further jackets.

From the foregoing description taken in connection with the accompanying drawings it is thought the construction, operation and advantages of my invention will be clear to those skilled in the art.
